In the call, a member of the Beverly Hilton's security staff requested paramedics for a 46-year-old woman. He never identifies her as Houston.

"I'm not sure she fell or if she was in the bathroom with the water," the caller said.

The caller -- who is not named in the recording -- said an "irate" woman first alerted security to the situation.

Houston was found face-down in her hotel bathtub on Feb. 11. Her accidental death was attributed to drowning partially to blame on heart disease and cocaine use, according to the coroner's report.
